720   Ethernet adapter that was previously present has not been detected.

Explanation

An Ethernet adapter that was previously present has not been detected.

Data:
  • A number indicating the adapter location. The location indicates an adapter slot. See the node canister description for the definition of the adapter slot locations. If the location is 0, the adapter is integrated into the system board or directly connected to it, that is, not in a PCI express expansion slot.

User response

  1. If possible, use the management GUI to run the recommended actions for the associated service error code.
  2. If the adapter location is 0, use the remove and replace procedures to replace the node canister.
  3. If the location is not 0, there are a number of possibilities:
    1. If you deliberately removed the adapter (for example, replacing it with a different adapter type), use the management GUI recommended actions to mark the hardware change as intentional.
    2. Use the remove and replace procedures to remove and open the canister and make sure the adapter is properly installed.
    3. If the previous steps have not isolated the problem, use the remove and replace procedures to replace the adapter. If this does not fix the problem, replace the canister.
